Review on 🔒 Enhancing Security with the LINEAR Ak-11 Exterior Digital Keypad by Adam Gechem

UPDATE (06/08/2017) It's been over a year and the keyboard has weathered a whole wet Northern California winter. It still works fine. The only design change I'll be making is replacing the useless keyboard backlight with an LED. The standard lighting is very poor even in the darkest light. I love well built products.======================================== = === ==========Housing, lock and key made of powder-coated die-cast aluminium. Looks really strong. I will update for durability. My last keyboard lasted 15 years. I bought a Heddolf M330-1KA which lasted 6 months. I hope this guy lasts longer. If you bought it, here is the essence of the programming. If you make a programming mistake, exit programming mode and re-enter programming mode. After programming is complete, be sure to exit programming mode before checking the programmed code. (The instructions were poorly written, and I've seen many people call support to get coding help.) Fortunately, I'm a programmer and I know how other programmers think when designing a user interface. I will increase the shelf life to 6 months (as far as I remember).
